I heard that teams would have to use a head to SB2 spec, fitted to their own engine. This included Ford and Pontiac! (?)
I couldn't quite see the blue oval going for GM products on their cars, or even how the parts would be compatible.
All teams use Ford axles and steering geometries, but this is to avoid expense and to ensure a steady supply of parts.
The cars are basically all the same design until the plastic caps are fitted front and rear. Until the car recieves it's final sheet metal, the chassis are identical.
The engine is what differentiates the cars, and to do this would destroy a long heritage of inter-marque rivalry.
Just my opinion.
